Jacob served as the Military Assistant Secretary to the War Cabinet for the duration of the [[Second World War]] (he actually asked to be returned to his regiment in 1940, but was refused). He worked closely with Winston Churchill and implemented Churchill's communications during his thirteen wartime journeys outside the [[United Kingdom]]. Churchill valued Jacob's efforts enough to endorse his promotion from the rank of [[colonel]] to [[lieutenant general]] over the course of the war. As a brigadier (war-substantive lieutenant-colonel), Jacob was promoted to the substantive rank of colonel in the Regular Army on 30 June 1943.<ref>{{London Gazette|issue=36160|supp=y|page=3965|date=3 September 1943}}</ref> He was granted the acting rank of major-general on 8 September 1944 and advanced to temporary major-general on 8 September 1945.<ref>{{London Gazette|issue=36721|supp=y|page=4475|date=26 September 1944}}</ref><ref>{{London Gazette|issue=36721|supp=y|page=4890|date=2 October 1945}}</ref> In the 1944 Birthday Honours, he was appointed a Companion in the Military Division of the [[Order of the Bath]] (CB).<ref>{{London Gazette|issue=36544|supp=y|page=2567|date=2 June 1944}}</ref>
